How to use Merge PDF

  1. Add the PDF files you want to combine.

  2. Drag the filenames into the order the documents should appear.

  3. Remove any file you don't need with the × button.

  4. Click Merge PDFs and download the combined file.

About this tool

Merging copies every page from your PDFs into a new document in the order you choose, without re-rendering pages — text stays selectable and quality is untouched. Because the work is done by an open-source PDF library running in your browser, there is no upload step, no queue and no file retention: closing the tab removes everything.

This is often the last step in assembling a complete document from separate parts — a cover letter and a resume, several signed contract pages scanned separately, or chapters of a report drafted by different people — combined into the single file most systems expect to receive.

Common ways people use this

  • Combining a cover letter and resume into a single PDF for a job application
  • Merging several signed pages of a contract that were scanned separately
  • Assembling chapters or sections from different files into one complete report

Tips for better results

  • Add all your files first, then use the up/down arrows to set the final order — it's easier than trying to add them in perfect order from the start.
  • Run the PDF Page Counter on the merged result afterward if you need to confirm the total page count matches what you expected.

Frequently asked questions

Does merging reduce PDF quality?
No. Pages are copied, not re-rendered — text remains selectable and images keep their original resolution.
Can I reorder the files before merging?
Yes. Drag entries in the file list; the merged PDF follows that exact order.
Can password-protected PDFs be merged?
Encrypted PDFs cannot be read without their password, so they can't be merged here. Remove the protection in the application that created the file first.
Are my documents stored anywhere?
No. Merging happens in your browser's memory. Nothing is uploaded, and nothing persists after you leave the page.
How many PDFs can I merge at once?
Up to 20 files in a single batch, combined into one output document in the order you set.
